Description

내연기관의 흡입장치 {ADMISSION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE}Suction device of internal combustion engine {ADMISSION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE}

본원 발명은 독립항의 전제부에 따른 내연기관, 특히 차량 엔진을 위한 흡입 장치에 관한 것이다.The invention relates to an intake apparatus for an internal combustion engine, in particular a vehicle engine, according to the preamble of the independent claim.

독일 특허 OS 41 10 597 호에는 흡입장치로서 형성되어 있는, 다기통 내연기관의 유입계통이 공지되어 있다. 이와 같은 공기 흡입 장치에는 다수의 흡입관이 필요한데, 이러한 흡입관은 매니폴드 통로로부터 흡기된 정화 공기를 엔진의 실린더 헤드에 있는 각각의 흡기 포트(aspirating port)로 공급한다. 흡입장치는 일반적으로 알루미늄이나 합성수지로 되어 있으며, 주조 또는 사출성형에 의해 제조된다.German patent OS 41 10 597 discloses an inlet system of a multicylinder internal combustion engine, which is formed as a suction device. Such an air intake device requires a plurality of intake tubes, which supply purified air taken in from the manifold passages to respective aspirating ports in the cylinder head of the engine. Suction devices are generally made of aluminum or synthetic resin and are manufactured by casting or injection molding.

이러한 흡입장치의 단점은 복잡한 제조공정에 있다. 예를 들어, 용융 코어 공법(core melting process)에 의해 흡입장치를 제조하는 것이 공지되어 있는데, 여기서는 후에 흡입장치의 중공실을 형성하는 금속제의 코어가 합성수지 재질에 싸여지고, 이후 이 금속제 코어가 용융되어 나온다. 또한, 이와 같은 합성수지 재질의 공기 흡입장치는 다중 쉘 기법(multiple shell technique) 즉, 개개의 합성수지 쉘을 형성한 후 이들을 서로 용접시키는 기법에 의해 제조될 수도 있다.The disadvantage of this suction device lies in the complicated manufacturing process. For example, it is known to manufacture a suction device by a core melting process, in which a metal core, which later forms the hollow chamber of the suction device, is wrapped in a synthetic resin material, after which the metal core is melted. Comes out. In addition, the synthetic resin air intake device may be manufactured by a multiple shell technique, that is, a technique of forming individual synthetic resin shells and welding them together.

본원 발명의 실시예가 도면에 나타나 있으며, 또한 이하에서 설명된다.Embodiments of the invention are shown in the figures and further described below.

도 1은 개략적으로 도시된 흡입장치의 단면도이고,1 is a cross-sectional view of the suction device schematically shown,

도 2는 합성수지 중공 성형부와 연결 플렌지간의 결합부를 상세히 도시한 도면이며,Figure 2 is a view showing in detail the coupling between the synthetic resin blow molding and the connecting flange,

본원 발명의 과제는 상기의 단점을 없애고, 제조가 간단하며 조립비용이 적게 소요되는 흡입장치를 제조하는데 있다. 이러한 과제는 본원발명에 따른 독립항의 제특징에 의하여 해결된다.An object of the present invention is to eliminate the above drawbacks, to manufacture a suction device that is simple to manufacture and low assembly cost. This problem is solved by the features of the independent claims according to the present invention.

본 발명사상의 핵심은, 제조과정을 현저히 복잡하게 하는 극히 불규칙적인 형태의 공기 흡입관을 하나 이상의 중공 성형부(blow-molded part)로 제조하고, 이러한 부분들을 간단한 구조의 추가적인 합성수지 부품 또는 플렌지 요소에 결합시키는 것에 있다. 중공성형부를 연결 플렌지 및 기타 요소들과 결합시키는데 있어서, 진동을 전달하지 않도록 연결하는 것이 가능하다. 이는 결합되는 양 구성요소 사이에 탄성 재료가 조립 사출 성형과정(assembly injection-molding process)에 의해 장착된다는 것을 의미한다. 이러한 탄성 재료는, 한편으로는 양 구성요소 사이의 확실한 결합을 제공하는 동시에, 다른 한편으로는 양 구성요소 사이에 진동이 전달되는 것을 방지한다.The essence of the present invention lies in the manufacture of one or more blow-molded parts of extremely irregularly shaped air intake tubes, which significantly complicates the manufacturing process, which is then incorporated into additional synthetic resin parts or flange elements of simple construction. It is to combine. In joining the blow molding part with the connecting flange and other elements, it is possible to connect so as not to transmit vibrations. This means that the elastic material is mounted by an assembly injection-molding process between both components to be joined. Such an elastic material, on the one hand, provides a secure coupling between both components, while on the other hand prevents transmission of vibrations between both components.

중공 성형부를 사용하는데 따른 추가적인 이점은, 진동관 길이를 가변적으로 만들 수 있다는, 즉 최적화가 별 어려움 없이 이루어 질 수 있다는 점에 있다.An additional advantage of using the hollow molded part is that the tube length can be made variable, that is, optimization can be made without any difficulty.

본원 발명의 바람직한 실시예에서는, 상기 구성요소를 합성수지의 중공 성형에 의해 제조하지 않고, 열가소성 합성수지의 사출 성형법에 의해 제조한다.In a preferred embodiment of the present invention, the above components are not manufactured by blow molding of synthetic resin, but by injection molding of thermoplastic synthetic resin.

또한 본원 발명의 실시예에 따르면, 하나 이상의 흡입관에 추가 연결부가 제공되며, 이 연결부가 스위치 수단과 연결되거나 또는 분리되게 한다. 이러한 추가연결부에 의해, 모터의 속도 및 그 부하량에 따라 개방되거나 폐쇄되는 추가 덕트가 흡입장치에 제공될 수 있다.Also in accordance with an embodiment of the present invention, one or more suction pipes are provided with further connections, which are connected or separated from the switch means. By this additional connection, an additional duct can be provided in the suction device, which is opened or closed depending on the speed of the motor and its load.

고도로 정밀한 합성수지 부품을 제작하기 위해, 유리섬유 강화 열가소성 합성수지(glass fiber reinforced thermoplastic synthetic resin)로 제작할 수도 있으며, 여기서 유리섬유는 소위 장섬유(long fiber)이다. 이러한 장섬유는 합성수지재료에 이방성으로 묻히어 합성수지 재료의 인장 특성을 등방성으로 만든다는 장점을 가지고 있다. 바람직하게는, 합성수지 재료로 폴리프로필렌(polypropylene)이나 폴리아미드(polyamide)가 사용될 수 있다. 집합장치(collecting unit)의 간단한 제조에 의해, 스로틀 밸브, 공기 유량계, 및 기타 필요한 구성요소등과 같은 추가적 부품들이 그 안에 일체로 내장될 수 있게 된다.To produce highly precise synthetic resin parts, it may also be made of glass fiber reinforced thermoplastic synthetic resin, where the glass fiber is the so-called long fiber. Such long fibers have an advantage that they are anisotropically buried in a synthetic resin material to make the tensile properties of the synthetic resin material isotropic. Preferably, polypropylene or polyamide may be used as the synthetic resin material. The simple manufacture of a collecting unit allows additional components such as throttle valves, air flow meters, and other necessary components to be integrated therein.

본원발명에 따른 실시예의 여타 특징들은 청구범위뿐만 아니라 명세서 및 도면에 의해 명백해 질 것이며, 각각의 특징들은 개별적이거나 또는 각각 조합된 다양한 형태로서 본원발명의 실시예 및 여타 분야에서 구체화 될 수 있으며, 여기서 청구되는 각각의 실시예를 구성하게 된다.Other features of embodiments in accordance with the present invention will be apparent from the description and drawings, as well as from the claims, each of which may be embodied in the embodiments of the present invention and other fields in various forms, either individually or in combination. Each embodiment constitutes the claimed subject matter.

도 1에는 흡입관(10), 플렌지(11), 및 커버(13)를 구비한 집합장치(12)를 포함하는 흡입장치가 도시되어 있다. 집합장치에는 스위칭 실린더(switching cylinder; 14)가 있는데, 이 스위칭 실린더는 여기에 도시된 위치에서 개구부(15)를 집합장치(12)에 연결하고 있다. 흡입관은 접합부(16)에서 플렌지(11)에 연결되며, 접합부(17)에서 접합장치(12)에 연결된다. 전체 흡입장치는 플렌지(11)에 의해 내연기관의 실린더 헤드(도시되지 않음)에 고정되어 있으며, 그 반대측에서 지지부또는 고정부재(도시되지 않음)에 지지되어 있다.1 shows a suction device comprising a collection device 12 having a suction pipe 10, a flange 11, and a cover 13. The assembly has a switching cylinder 14 which connects the opening 15 to the assembly 12 at the position shown here. The suction pipe is connected to the flange 11 at the junction 16 and to the junction 12 at the junction 17. The entire suction device is fixed to the cylinder head (not shown) of the internal combustion engine by the flange 11, and is supported by the support or the fixing member (not shown) on the opposite side.

접합부(16) 및 접합부(17)는 도 2에 상세히 도시되어 있다. 합성수지 재료로 제조된 흡입관(10)은 약간의 간극을 둔 채 플렌지 요소(18)를 덮고 있다. 이 두 부품이 서로 결합된 후, 상기 간극이 소위 조립 사출 성형과정(assembly injection- molding process)에 의해 탄성중합체, 예를 들어 TPE 등으로 채워진다. 이러한 탄 성중합체는 양 부품간에 마찰접속적 결합(positive junction) 및 형상접속적 결합(mating junction)을 형성한다. 더욱이, 이러한 탄성중합체는 플렌지 요소(18)를 통하여 흡입장치로 전달되는 진동을 효과적으로 감쇄시키기에 적합하다. 또한 집합 장치(12)와 흡입관(10) 사이에 있는 개구부(15)도 탄성중합체 재료로 형성될 수 있다. 따라서 하나의 구성요소로부터 다른 구성요소로의 진동 전달이 방지된다.The junction 16 and the junction 17 are shown in detail in FIG. 2. The suction tube 10 made of synthetic resin material covers the flange element 18 with a slight gap. After the two parts are joined together, the gap is filled with an elastomer, for example TPE, by means of a so-called assembly injection-molding process. This elastomer forms a positive junction and a mating junction between the two parts. Moreover, such elastomers are suitable for effectively attenuating vibrations transmitted through the flange element 18 to the suction device. The opening 15 between the assembly device 12 and the suction tube 10 may also be formed of an elastomeric material. Thus, vibration transmission from one component to another is prevented.

도 3에는 흡입장치의 평면도가 도시되어 있다. 각각의 흡입관(10a ∼ 10f)은 3개의 흡기관으로 구성된 그룹을 형성하고 있다. 하나의 그룹은 오직 하나의 관으로부터 흡입된다. 이 관은 흡입관 사이에 끼어져서 두개의 핀치 심(pinch seam;19,20 또는 19a, 20a)이 형성된다. 양 관 그룹은 하나의 작업과정에서 플렌지(11) 및 집합장치(12)에 결합될 수 있다. 집합장치에는 공기의 유량을 제어하기 위하여 스로틀 밸브가 결합될 수 있으며, 이러한 스로틀 밸브는 여기에 개략적으로 도시되어 있다. 물론, 밸브나 오일 분리기와 같은 추가적인 부품들이 집합장치에 연결될 수도 있다3 shows a top view of the suction device. Each suction pipe 10a-10f forms the group which consists of three intake pipes. One group is drawn from only one tube. This tube is sandwiched between the suction tubes to form two pinch seams 19, 20 or 19a, 20a. Both pipe groups can be coupled to the flange 11 and the assembly device 12 in one operation. The assembly may be coupled with a throttle valve to control the flow of air, which is shown schematically here. Of course, additional components such as valves or oil separators can also be connected to the assembly.

본원발명에 따른 내연기관의 흡입장치는 제조가 간단하며 조립비용이 적게 소요되는 등의 다양한 이점으로 인해 내연기관의 흡입장치로서의 사용이 유망시 된다.The suction device of the internal combustion engine according to the present invention is promising to be used as the suction device of the internal combustion engine due to various advantages such as simple manufacturing and low assembly cost.
